JP 2003-46967 A

  For example, when assuming a scene in which a joint performance with a remote karaoke device is used when performing karaoke only in a private room such as a karaoke box, the technique described in Patent Document 1 has the following inconvenience. it is conceivable that.

  When enjoying karaoke only in a private room in a private room, not only music for performing joint performance with a remote karaoke device, but also music that is played only in your own room by other users who do not participate in the joint performance It may be requested. In such an environment, when a performance order list is shared among a plurality of karaoke devices, the music reserved uniquely in the partner karaoke device is also played in the own room, so the music reserved in the karaoke device in the own room Will be waiting for the performance.

  The present invention has been made to solve the above problems. An object of the present invention is to provide a technique for synchronizing the performance times of music pieces to be jointly played among a plurality of karaoke devices while each karaoke device performs performance time series control of reserved songs according to their own performance order list. Is to provide.

  The karaoke apparatus of the present invention has a function of performing a joint performance among a plurality of karaoke apparatuses, and includes a performance control means, a determination means, a registration means, a waiting time calculation means, and a waiting time acquisition means. And adjusting means. The performance control means sequentially plays the music according to the performance order list representing the performance order of the music reserved for performance in the own karaoke apparatus. A determination means determines execution of joint performance between other karaoke apparatuses. The registering means registers the joint performance music performed in the joint performance determined by the determining means at the last position of the performance order list.

The waiting time calculating means calculates a waiting time until the performance order of the joint performance music arrives based on the performance time length of the music other than the joint performance music in the performance order list. The waiting time acquisition means acquires the waiting time until the performance order of the joint performance music arrives for each of the other karaoke apparatuses participating in the joint performance determined by the determination means.

  The adjusting means specifies the minimum waiting time among the waiting time calculated by the waiting time calculating means and the waiting time of the other karaoke apparatus acquired by the waiting time acquiring means. Then, the adjusting means adjusts the waiting time of itself to the minimum waiting time by shortening the playing time length of the other music piece in the performance order list. On the other hand, the performance control means plays the music according to the editing that shortens the performance time length for the other music edited so as to shorten the performance time length by the adjusting means.

  According to the present invention, instead of sharing a performance order list among a plurality of karaoke devices participating in a joint performance, each karaoke device registers a joint performance song in a performance order list managed individually, It is possible to perform time series control of reserved music according to a unique performance order list. Thereby, even if it is a case where a joint performance is performed, the performance order of the music reserved with the own karaoke apparatus is not influenced by the performance condition of the music reserved with the other karaoke apparatus.

  Furthermore, based on the waiting time of the other karaoke devices participating in the joint performance, the waiting time until the performance order of the joint performance music arrives in the performance order list of the own karaoke device can be adjusted. Thereby, the performance time of a joint performance music can be synchronized among several karaoke apparatuses which participate in a joint performance.

  By the way, when shortening the performance time length of music other than the joint performance music in the performance order list, as shown in claim 2, it is preferable to shorten the subsequent part of the music. By shortening the posterior part of the music, that is, the accompaniment part after the singing is finished, it is possible to shorten the performance time without affecting the singing of the music.

  The karaoke apparatus according to claim 3 has the following characteristics. In other words, each piece of music registered in the performance order list is associated with identification information of the user who requested each piece of music. Then, the adjusting means identifies the user related to the joint performance, and among the music other than the joint performance music in the performance order list, the performance time length of the music requested by the user related to the singing of the joint performance music. Shorten preferentially. By doing in this way, in order to synchronize the performance time of a joint performance music with another karaoke apparatus, when reducing the performance time of another music, the user who is not related to a joint performance music can be considered.

  In the karaoke apparatus according to claim 4, the waiting time is adjusted by the waiting time calculating means, the waiting time obtaining means, and the adjusting means each time one piece of music in the performance order list is played by the performance control means. Features. By doing this, even if the performance order of the performance order list is changed by canceling or interrupting the reservation before the performance order of the joint performances arrives, the waiting time is resumed. Can be adjusted.

  By the way, in the own performance order list, the waiting time until the performance order of the joint performance music arrives is within a range that can be adjusted only by shortening the music performance time length with respect to the minimum waiting time in other karaoke devices. Deviating situations are also possible. Therefore, it is preferable to perform as described in claim 5. In other words, the adjusting means determines whether or not the waiting time can be adjusted to the minimum waiting time by shortening the performance time length of the music. Advance the playing order. By doing in this way, the flexibility which can adjust own waiting time according to minimum waiting time can be made high.

Next, the karaoke system according to claim 6 has a plurality of karaoke apparatuses communicable through a network, and has a function of performing joint performance among the plurality of karaoke apparatuses. Each of the plurality of karaoke apparatuses constituting the karaoke system of the present invention includes a performance control means, a determination means, a registration means, a waiting time calculation means, a waiting time acquisition means, as in the karaoke apparatus according to claim 1. And adjusting means. According to the karaoke system of the present invention, the effect described in the karaoke apparatus according to claim 1 can be obtained.

  In addition, as described in claim 7, the present invention can be realized as a program executed in a computer or a storage medium for storing the program.

The communication interface unit 12 is a communication device that connects the karaoke apparatus 10 to the Internet 100 and controls communication via the Internet 100. The karaoke device 10 communicates with other karaoke devices 10 via the communication interface unit 12.

The storage unit 13 is a storage device composed of, for example, a hard disk drive or a semiconductor memory. The storage unit 13 stores a karaoke database in which a lot of music data for playing karaoke music is recorded and a program for controlling the operation of the karaoke apparatus 10. Note that the music data recorded in the karaoke database includes information representing performance sections such as preludes, main parts, interludes, and followers as performance information for controlling the performance of the music, and the performance of the entire music and each performance section. It is assumed that information indicating the time length is included. The operation unit 14 is an input device for inputting an operation from a user, and includes a touch panel, a key switch, and the like provided in the karaoke apparatus 10 main body.

  The voice input / output unit 15 is a device that controls voice input / output. A microphone 17 is connected to the input side of the voice input / output unit 15. Thereby, the voice input / output unit 15 acquires the user's singing voice. A speaker 18 is connected to the output side of the voice input / output unit 15. Thereby, the voice input / output unit 15 outputs the performance sound of the music reproduced in the performance process by the control unit 11 and the sound source signal of the user's singing voice to the speaker 18. The speaker 18 converts the sound source signal output from the audio input / output unit 15 into sound and outputs the sound.

  The display 16 is a display device that displays video based on video data sent from the control unit 11. The camera 19 is an imaging device installed in a place (for example, a karaoke room) where the karaoke device 10 is installed. The camera 19 captures an image of a singer who performs karaoke singing using the karaoke device 10. Data is output to the control unit 11.

  When the control unit 11 receives a music request from a user via an electronic sample device (not shown) such as a remote control terminal, the control unit 11 associates the music number of the music with the identification information of the requested user, and stores the internal RAM.

For this reason, the karaoke apparatus 10 includes a clock 20 as a time measuring means for acquiring time and measuring the remaining time until the start of performance.

  In the karaoke system 1 of the present embodiment, the karaoke apparatuses 10 participating in the joint performance can wait for the performance order of the joint performance songs in the performance order list in each karaoke apparatus 10 so that the joint performance songs can be played simultaneously. Process to adjust the time. A series of detailed procedures will be described later. Since other functions and configurations of the karaoke apparatus 10 are in accordance with known techniques, detailed description thereof is omitted here.

[Explanation of joint performance processing]
The procedure of the joint performance process which the control part 11 of each karaoke apparatus 10 with which the karaoke system 1 is provided is demonstrated, referring the flowchart of FIG. This process is a process executed when a request for a piece of music to be performed jointly is received from the user. This process is also executed in the same manner when a joint performance is proposed from another karaoke apparatus 10.

  In S100, the control part 11 performs negotiation regarding joint performance by communicating between the other karaoke apparatuses 10. FIG. Specifically, the information regarding various conditions (for example, music to be played) regarding the joint performance is exchanged with the other karaoke apparatus 10 and the other karaoke apparatus 10 is inquired of whether or not to participate in the joint performance. .

  In S102, the control part 11 judges whether joint performance with the other karaoke apparatus 10 is materialized as a result of the negotiation in S100. Here, it is determined that the joint performance is established on the condition that an answer indicating that participation in the joint performance is possible is obtained from another karaoke apparatus 10. When the combined performance is established (S102: YES), the control unit 11 proceeds to S104. On the other hand, when the joint performance is not established (S102: NO), the control unit 11 ends this process.

  In S104, the control unit 11 registers the music played in the joint performance (hereinafter referred to as the joint performance music) at the end of the current performance order list in association with the identification information of the singing user. Here, as illustrated in FIG. 4, the same joint performance music is registered at the last position in the performance order list managed by each of the karaoke apparatuses 10a, 10b, and 10c participating in the joint performance. In the example of FIG. 4, in the performance order list of the karaoke apparatus 10a (store A), normal reserved songs that are not the targets of the joint performance are registered from the first to the fifth, and the user a is the singer in the sixth. Assume that a joint performance is registered. Moreover, in the karaoke apparatus 10b (store B), the normal reserved music which is not the object of a joint performance is registered to the 1st-4th, and the joint performance music is registered 5th as the singer. Shall. Moreover, in the karaoke apparatus 10c (store C), the normal reserved music which is not the object of a joint performance is registered to the 1st-3rd, and the joint performance music is registered for the user e as a singer 4th. Shall.

  Returning to the flowchart of FIG. In S106, the control unit 11 calculates a waiting time until the performance order of the joint performance music comes based on the performance order list. Specifically, the control unit 11 refers to the karaoke database for each reserved song registered higher than the jointly performed song in the performance order list, obtains the performance time length, sums them up, and waits for the waiting time. calculate. Here, in each of the karaoke apparatuses 10 participating in the joint performance, the waiting time until the performance order of the joint performance music arrives is calculated based on the respective performance order list (hereinafter simply referred to as the waiting time).

  In S108, the control part 11 acquires the waiting time calculated in each of the other karaoke apparatuses 10 which participate in a joint performance. At this time, each karaoke device 10 transmits its own waiting time in response to a waiting time acquisition request from another karaoke device 10. Thereby, the waiting time information is shared among the karaoke apparatuses 10 participating in the joint performance. In S110, the control unit 11 compares the own waiting time calculated in S106 with the waiting time of the other karaoke apparatus 10 acquired in S108, and determines whether or not the own waiting time is the shortest. To do. When the own waiting time is the shortest (S110: YES), the control unit 11 proceeds to S118. On the other hand, when the own waiting time is not the shortest (S110: NO), the control unit 11 proceeds to S112.

  In S112, the control unit 11 adjusts its own waiting time to the shortest waiting time determined in S108 under the condition of shortening the subsequent performance of the reserved music registered higher than the joint performance music in the performance order list. It is determined whether or not it is possible. Specifically, the control unit 11 refers to the karaoke database for the reserved music registered higher than the joint performance music in the performance order list, and acquires the performance time length of the later performance part. Then, the control unit 11 keeps its own waiting time within a predetermined range based on the shortest waiting time on the condition that the subsequent playing is shortened within a possible range based on the acquired performance time length of the succeeding portion. It is determined whether or not it can be adjusted.

If it is determined that the waiting time can be adjusted to the shortest waiting time under the condition for shortening the follow-up (S112: YES), the control unit 11 proceeds to S114. In S114, the reserved music registered higher than the joint performance music in the performance order list is adjusted so that its own waiting time is adjusted to the shortest waiting time by performing editing for shortening the subsequent performance. Here, the control unit 11 shortens the performance time length of the sequel of the reserved song to be edited so that its own waiting time falls within a predetermined range based on the shortest waiting time.

  Moreover, the control part 11 gives priority to the reservation music requested | required by the user matched as a singer of a joint performance music among the reservation music registered higher than a joint performance music in the performance order list. Select for editing. Further, as an editing method for shortening the later performance, for example, all or a part of the later performance portion is cut by fading out.

  A specific example of S114 will be described with reference to FIG. In the example of FIG. 5, it is assumed that the waiting time of the karaoke device 10c is the shortest in the performance order list managed by each of the karaoke devices 10a, 10b, 10c participating in the joint performance. That is, in this situation, editing is performed in the karaoke apparatuses 10a and 10b so that the respective waiting times match the waiting times of the karaoke apparatus 10c.

  As illustrated in FIG. 4, in the performance order list of the karaoke apparatus 10 a (store A), the first, second, and fifth reserved songs requested by the user a associated as a singer of the jointly performed music are , It is preferentially selected as an editing target for shortening the later performance. In the karaoke apparatus 10a, as long as the waiting time can be adjusted to the shortest waiting time by editing only the reserved song requested by the user a, the third and fourth reserved songs requested by the other user b are used. Is excluded from editing.

  In addition, in the performance order list of the karaoke apparatus 10b (store B), the first, second, and third reserved songs requested by the user c associated as a singer of the jointly performed music are edited to shorten the subsequent performance. It is preferentially selected as a target. In the karaoke apparatus 10b, as long as the waiting time can be adjusted to the shortest waiting time by editing only the reserved song requested by the user c, the fourth reserved song requested by the other user d is edited. Not subject to

  Returning to the flowchart of FIG. If it is determined in S112 that the waiting time cannot be adjusted to the shortest waiting time under the condition for shortening the subsequent performance (S112: NO), the control unit 11 proceeds to S116. In S116, the control unit 11 increments the performance order of the joint performance songs in the performance order list by one. After S116, the control unit 111 returns to S106.

  On the other hand, in S118, the control unit 11 determines whether or not the performance order of the joint performance music has arrived based on the performance order list. If the performance order of the joint performance has not arrived (S118: NO), the control unit 11 proceeds to S120. In S120, a normal reserved song is played based on the performance order list. Here, with respect to the reserved music that has been edited to shorten the later performance in S114, the performance is performed by reflecting the editing that shortens the later performance. After the performance of one piece of music is completed in S120, the control unit 11 returns to S106.

  On the other hand, when it determines with the performance order of a joint performance music having arrived in S118 (S118: YES), the control part 11 progresses to S122. In S122, the control part 11 performs a joint performance music. At this time, the control part 11 starts performance of a joint performance music in time with each karaoke apparatus 10 which participates in joint performance. After S122, the control unit 11 ends this process.

For example, the following (1) to (3) can be considered as a method for starting performance at the same timing between the karaoke apparatuses 10 participating in the joint performance.
(1) It is a requirement that the time represented by the clock 20 is consistent among the karaoke apparatuses 10. (2) Based on the length of the waiting time until the performance order of the joint performance music arrives in the performance order list of each karaoke device 10 and the time represented by the clock 20 of each karaoke device 10, the joint performance is performed in each karaoke device 10. The timing (time) at which the performance of the music starts is set as the reference time.
(3) Each karaoke device 10 matches the respective waiting time with the shortest waiting time by the processing of S106 to S116 described above, thereby matching the reference time among the karaoke devices 10, and each karaoke device at the reference time. The device 10 starts playing the joint performance.

[effect]
The karaoke system 1 according to the embodiment has the following effects.
Rather than sharing a performance order list among a plurality of karaoke apparatuses 10 participating in the joint performance, the performance order list managed individually by each karaoke apparatus 10 is registered, and each performance order is unique. It is possible to perform performance time series control of reserved songs according to the list. Thereby, even if it is a case where a joint performance is performed, the performance order of the music reserved with the own karaoke apparatus 10 is not influenced by the performance condition of the music reserved with the other karaoke apparatus 10.

  Furthermore, the waiting time of the own karaoke device 10 can be adjusted based on the waiting time of the other karaoke devices 10 participating in the joint performance. Thereby, it can be made easy to synchronize the performance time of a joint performance music between the some karaoke apparatuses 10 which participate in a joint performance.

  In addition, when shortening the performance time length of other songs in the performance order list other than the joint performance songs, by reducing the subsequent part of the music, that is, the accompaniment part after the singing is finished, the singing of the music is affected. The performance time can be shortened without affecting the performance. Moreover, the other reserved music requested by the singer of the joint performance music can be preferentially edited. By doing in this way, when shortening the performance time of other reserved music by the convenience of joint performance, it can consider the user who is not related to joint performance.

  Moreover, the control part 11 can adjust waiting time, whenever the performance of the music based on a performance order list | wrist is performed. By doing this, even if the performance order of the performance order list is changed by canceling or interrupting the reservation before the performance order of the joint performances arrives, the waiting time is resumed. Can be adjusted.

[Modification]
In the above-described embodiment, the case where the joint performance is performed by the three karaoke apparatuses 10a, 10b, and 10c has been described. The present invention is not limited to this, and the present invention may be such that a combined performance is performed by more than three karaoke apparatuses 10, and a combined performance (so-called remote duet) is performed by two karaoke apparatuses 10. It may be. Moreover, in the above-mentioned embodiment, the case where the some karaoke apparatus 10 was connected so that communication was possible via the internet 100 was demonstrated.
